The increased need for effective school leadership development, especially in rural and high-needs schools, has led to an increase in research-practice partnerships between districts and universities. Yet, there is a need for systematic analysis of the outcomes of such partnerships. The purpose of this paper is to examine the influence of a leadership development initiative on 16 school leaders and eight leadership coaches and their leadership and leadership coaching practices. The initiative, the Leadership Learning Community (LLC), was created through a research-practice partnership between a consortium of 12 predominantly rural, high-poverty school districts and two universities to meet the districts' leadership development needs. The results of the study demonstrate the benefits of rural school districts partnering with other districts and universities to provide cross-district leadership development through facilitated professional communities and job-embedded coaching to develop rural school leaders and coaches able to lead continuous school improvement efforts.
